EIHRAIM ll. SPEDDING, OF LOWELL, MASSACHUSETTS.

LOOM-TEMPLE.

Application filed February 3, 1908.

Massachusetts, have invented a certain new Specification of Letters Patent.

and useful Improvement in Loom-Temples,

of which the following is a specification, reference being had therein to the accompanying drawings.

The object of the invention is to provide means for correcting a tendency to transverse tipping of the slide-bar or shank and the temple-head and roll of a loometemple as a result of wear of the contacting surfaces of the slide-bar or shank and the stand in which the said slide-bar is mounted, and for enabling, if desired, the said wear to be prevented or delayed.

The invention consists in an offset contactpiece which is carried by the heel-piece connected with the slide-bar or shank of a loomtemplc, and which contact-pieee engages a guide upon the temple-stand to restrain the bar or shank and the parts which are carried thereby from tipping.

The invention consists, further, in making the contact-piece adjustable.

The invention admits of being variously embodied and applied, without involving departure from the principles thereof. I have shown in the drawings a variety of embodiments.

In the drawings'Figure l shows in elevation a loom-temple having an embodiment of the invention applied thereto, the front portion of the stand being omitted. Fig. 2 is a plan of the parts which are shown in Fig. l, a small portion of the top of the stand be ing broken away at the right. Fig. 3 is a view in cross-section on line 3, 3, of Figs. l and 2, looking in the direction indicated by the arrows at the ends of such line. Fig. 4 is a plan, detached, of the heel-piece and the contact-piece with which it is provided, forming a part of the temple shown in Figs. 1, 2 and 3. Fig. 5 shows 1n side elevation a different form of temple with a different embodiment of the invention applied thereto.

Fig. 6 shows in plan the parts of Fi 5. Fig. 7 shows in side elevation detache the block of Figs. 5 and 6, with its aide-face.

Fig. 8 is an elevation of the said b ook, viewin the rear end thereof. Fi 9 shows in si e elevation another embodiment of the invention. Fig. 10 shows the (parts of Fig. 9 in plan. Fig. 1l is a rear en elevation of Patented Nov. 3, 1908.

Serial No. 413,935.

the block of Figs. 9 and l0. Fig. l2 is a plan of the heel-piece.

Having reference to the dra\vings,-in the case of each embodiment of the invention the temple-stand is designated l, the shank or slide-bar of the temple is designated 2, the cap at the rear end of the shank or slide-bar is designated 3, the trough being indicated 4, and in each embodiment the heel-piece is pro vided with the heel or bun-ter l which. receives the pressure of the lay as the latter advances toward the breast-beam.

In the use of a temple upon a loom the tendency of the web in process of being woven to contract widthwise transmits to the roll that is inclosed within the cap and trough, and consequently to the rear end of the shank or slidebar 2, a pull toward the middle of the loom. This pull is exerted upon the roll at a` point below the longitudinal axis of the shank or slide-bar, and Consequently not only acts to draw the rear end of the shank or slide-bar inwardly toward the middle of the length of the loom, but also tends to rotate the slidebar around the said axis within the stand. Thereby the inner vertical side of the slide-bar is pressed against the inner vertical guidesurface at the rear end of the stand, the pressure be ing greatest at and adjacent the bottoms of the said inner side and guide-surface. The tendency to rotate the slide-bar or shank also acts in most cases to cause unequal pressure in like manner elsewhere between contacting surfaces of the shank or slide-bar and guide-surfaces of the stand. The result is that wear of the slide-bar or shank and of the guide-surfaces soon occurs in such manner as to permit the slide-bar or shank to turn upon its longitudinal axis under the influence of the inwardly acting strain of the web so that the cap, roll and trough assume a tipped position, nclining upward at their inner ends.

Fig. 3 of the drawings illustrates the wear which takes place at a in the case of the inner vertical guide-surface of the stand at the rear end of the latter, and at b in the case of the inner side of the squared portion of the slide-bar or shank. The tipping of the temple as aforesaid is undesirable, and in consequence thereof when temples have become worn as above ex lained they are usually discarded by manu acturers of cloth, new temples being substituted upon the looms.

In the case of the embodiment of the invention that is represented in Figs. l to 4, the contact-piece moving with the slide-bar or shank is designated 8, and at 9 is the guide with which such contact-piece engages to restrain the tendency of the Islide-bar or A shank and the parts which are carried thereby to tip or roll in the web. The contact-piece 8 is provided upon the heel-piece 6, Which is attached by screws 10, 10, to a forwardly-projecting lip ll on trough 4, so that thereby the contactpiece is carried by and caused to move with the slide-bar or shank. It rises from the outer portion of the heel-piece, being thereby somewhat offset with relation to the slidebar or shank, and extends forward parallel with the slide-bar or shank, its inner vertical surface bearing against the guide, which last is the outer surface of the upright side-portion of the lower section of the temple-stand. The engagement between the contactpiece and fixed guide is arranged to take place low down with relation to the slide-bar or shank, in order more eifectually to restrain the latter from tipping or rolling under the transverse pull of the web. The securing screws 10, 10, pass through holes 12, 12, in heel-piece 6, and forconvenience .in setting the contact-piece in applying the invention to a loom-temple, and in taking-up wear between the contactpiece and guide, the said holes are of Sullicient size transversely to permit the heelpieceand contact-piece to be adjusted transversely;

j ,Figs 5to 8 show an embodiment of the invention in which the heel-piece 6*L is secured to the forwardly extending lip 1la of the roll-trough by a single screw 10'l passing through a holeln in the heel-piece, such hole being transversely extended to permit of adjustment of the heel-piece and its Contacte piece transversely as above, and theeontactpiece SiL engages by its inner vertical face with the outer surface of the lug 1a ofthe templestand and with the outer surface of a lateral projection 13a from the vertically rocking detent-block 13, the latter being as usual louse under the strain of provided with a cated between the opposite lugs l, lb,

hen theoontact-pieee engages with the lateral projection 13a of the detent-block, it is not in all cases essential that it should also engage with the lug 1,

Figs. 9 to 12 show an embodiment of the invention in which the detent-block 13b is projection 13c having a downward extension 1.3 formed with an ear 13e that takes against the outer side of the temple-stand, for the sake of the support thereby afforded against inwardly acting pressure, and also formed with a foot 13t that is engaged by the outer side-Wall of a slot 6b in the heel-piece 6C. Heel-piece 6C is made laterally or transversely adjustable as in the case of heel-piece 6.

The invention is not limited to the precise details of construction which have been described herein, and in the'broader phases of the invention it is not limited to an immovable guide. The guide may if desired be constituted of a special piece or bracket conveniently attached to the temple-stand.

The invention may be applied to new temples for the purpose of reducing the rate of wear or practically preventing wear of the slide-bar or shank and the inner vertical guide therefor from occurring.

I claim as my invention r- 1. The combination with the temple-stand, and the reciprocating bar carrying the temple-roll, of a heel-piece provided with av guide-piece engaging a guide upon the temple-stand to restrain the bar and parts carried thereby from tipping.

2. The combination with the temple-stand, and the reciprocating bar carrying the temple-roll, of the transversely-adjustable heelpiece provided with a guide-piece engaging a guide upon the temple-stand to restrain the bar and parts carried thereby from tipf ping.

In testimony whereof I afiiX my signature in presence of two witnesses.
